Sawayaka Charcoal-Grilled Restaurant Kosai Hamanako

Located in Kosai City, this is the only branch in the city of Shizuoka’s famous hamburger steak chain, which operates 34 locations exclusively within Shizuoka Prefecture. The signature dish is the “Genkotsu Hamburg,” made from 100% beef formed into a thick block and grilled over charcoal. Served sizzling on a hot iron plate, the hamburger steak is cut in half right in front of you by the staff, after which you finish it to your preferred doneness. The bold, beefy flavor and firm, springy texture are outstanding. Sauces can be chosen from a classic onion sauce made with onions or a rich demi-glace, with a mixed option combining both also proving popular.

Don’t miss the Kosai Hamanako-exclusive menu items, made possible by a dedicated charcoal grill just for vegetables. Highlights include Charcoal-Grilled Chunky Vegetables, featuring seasonal produce cooked to a fragrant finish, and a Charcoal-Grilled Caesar Salad with romaine lettuce, whose smoky aroma and flavor are exceptional-dishes you can only enjoy at this location.

Beloved as a Shizuoka-only specialty, the restaurant attracts diners not just from across the prefecture but from other regions as well. Lines are common even outside peak hours, so be sure to allow plenty of time when you visit.
